[python] Filtering Pandas DataFrames on dates

I'm not allowed to write any comments yet, so I'll write an answer, if somebody will read all of them and reach this one.

If the index of the dataset is a datetime and you want to filter that just by (for example) months, you can do following:

df.loc[df.index.month == 3]

That will filter the dataset for you by March.
